New Garrett GTX-R Turbo's
I can't believe this hasn't been discussed on this forum yet. Looks like its only available in the LARGE turbo size right now, but eventually it will make its way down to one's we could use better.

Or you can get the PTE Billet turbo ;-)
Which you can get in the smaller sizes, rebuildable and air cooled...plus cheaper. |
oooooooooh. if they make a .86 A/R 3071 I might have a 2871R for sale.

Mentioned here! About halfway down in that pile of crap. https://www.miataturbo.net/forum/t40007/ |

Whoa, want more power or want to keep same power at less boost? __________________ Best Car Insurance | Auto Protection Today | FREE Trade-In Quote |
As far as I can tell, they're only talking about compressor wheels. And by "outline interchangeable" one might assume these new wheels will fit onto the current CHRAs and into the current housings, and be available as just a wheel upgade for those who don't want to buy whole new turbo. :dunno:

Also, Garrett doesn't sell raw wheels - if anything it'll be a new CHRA or a CHRA exchange. |
OOOO holyshizmofuck!
http://lolfed.com/wp-content/uploads...-very-nice.jpg jtothawhat can you tell us some about the comparable PTE product/technology? I tried to browse their turbos on their website but their website is broken. |

I think people haven't mentioned it here because 1. it's only big turbos so far 2. it will be out of the price range of most people here if/when they do make smaller turbos.
I've read about the PTE billet wheel turbos on the subaru forums. They say is a good thing to be air cooled only? I need to see some sort of logic on that. Otherwise I'd rather have water cooled Garrett CHRA. |
And they say there's nothing great for engineers to work on...
10% increases in flow and pressure ratio are RIDICULOUS design improvements....but it looks like the money is in the manufacturing technique here. Those compressor flow maps say all that needs to be said really. I'm impressed. |

Wow that told me nothing. All proprietary :/

I remember seeing superchargers with impellers that looked like this, back in the early 90's. (Paxton & early Prochargers). Think 50% efficient. Ha.

Call them up. OR go over to NASIOC proven power bragging and check out all the dyno sheets comparing new tech vs old tech. Lots of spool and power data over there. Frank |
This thread brings back bad memories of the Turbomachinery class I just completed. I cant look at a compressor wheel or volute the same way ever again :( . ew.

My old GT35R vs. my new PTE 6262 - evolutionm.net
Shows the difference with the new billet wheel compared to the "old technology" GT series. Keep in mind the 6262 is the same size as the GT35R. The 6262 even has a bigger hot-side. A lot of evo guys are running PTE Billet turbos; as well Subie guys and guys who have Grand Nationals. EDIT: PTE technology uses ceramic coated cartridge bearings, they're 100% rebuildable and require no water lines... |
